Loan Calculator on iPhone — no app, just Safari
Loan Calculator runs entirely in mobile Safari with no app to install. Here's the exact tap-by-tap flow for iOS users on any iPhone or iPad.
One reason people install third-party apps on their phone is that they don't realise the same tool runs perfectly in mobile browsers. Loan Calculator is browser-only — no app store, no install — and it works exactly the same on iPhone as it does on a laptop.
Run it in your browser: Loan Calculator — Runs entirely on your device using open web standards.
Step-by-step on iPhone
- Open Safari and go to Loan Calculator.
- Tap "Choose file" (or drag from the Files app if you're in split-screen on iPad).
- Pick the calculation from Photos, iCloud Drive, or Files — they all work.
- Set your options (sizes, quality, output format). Tap "Run" or whatever the equivalent button is for Loan Calculator.
- Save the result. Safari downloads to the iCloud Drive Downloads folder by default; tap the result and choose "Save to Files" if you need it somewhere specific.
- AirDrop or share it straight from the Files share menu — useful if the calculation is going to a Mac next.
Useful iOS-specific tricks
- Add Loan Calculator to your home screen to make it feel like a native app: tap the share button in Safari, scroll to "Add to Home Screen." It launches in its own window, no browser chrome.
- Use the Files app for batch input — select multiple calculations in Files, tap Share → Open in Safari, and Loan Calculator picks them all up at once.
- Photos library access works the same as any iOS app, but with no permissions to grant separately.

Why a browser tool beats most native apps for this
Native apps that calculate calculations are almost all just wrappers around browser-class libraries. They usually upload your file to their server, which is slower, less private, and sometimes paywalled. Loan Calculator does the work directly in your phone's browser engine — same code path that would run if you were on a desktop, no upload, no signup, no daily limit.
Frequently asked questions
Why isn't there a "Loan Calculator" app on the App Store?
Because there doesn't need to be. Mobile browsers run the same WebAssembly the desktop site uses. Shipping a native app would mean maintaining two codebases for the same feature.
Does it work on older iPhones?
Anything from the last five years handles Loan Calculator comfortably. Older devices may take longer for big files, but the underlying APIs (WebAssembly, FileReader) have been stable for years.
Is my calculation private when I use a browser tool?
Yes — more private than most apps, because nothing is uploaded. The calculation is processed entirely inside the browser tab and is gone the moment you close it.
Will processing drain my battery?
Heavy calculation work uses your phone's CPU just like any other intensive app. For most calculations the job finishes in seconds; a 100MB video might use a noticeable but small slice of battery.
